Kim Zolciak-Biermann is happy to share all the details about her plastic surgeries, and now her daughter Brielle Biermann is doing the same.

The Don’t Be Tardy stars talked to PEOPLE Now about why they went for their procedures.

Zolciak-Biermann, 40, says that she opted for the injections on her face, but her tummy tuck was out of necessity.

“I had a major hernia after my twins, so I had to have it repaired regardless, and they do it the same way almost as a tummy tuck, so I said you might as well do the repair, and I mean it was covered by insurance and the whole nine yards,” she says. “So I don’t know that I honestly would’ve done a tummy tuck, I feel like my stomach was pretty good, but I’m open with [her plastic surgeries].”

As for her face: “I’ve done my lips, I like Botox. I’ve gotten Botox from 23-on for migraines, so I’ve done it most of my life,” Zolciak-Biermann says.

But for her daughters, the former Real Housewives of Atlanta star says she won’t “let them do anything until they’re 18,” which was a problem for Biermann.

“Brielle was very insecure about her lips, I heard about it FOREVER,” her mom says. “And when she turned 18, she was like, I’m doing it. And I was like, well, I’m going to take you to the best, I’m not going to let you go to somebody who’s not good. So I did take her and I got a lot of heat for that, but it’s like, she’s going to do it anyway.”

Biermann, now 21, says that she was insecure about her lips “because I had none.”

“All my friends had beautiful, full lips,” she says. “Like my best friend Elizabeth. I was like, you bitch, I want lips that look like yours.”

And as soon as Zolciak-Biermann would let her, Biermann was ready.

“Since I was 14 I was like, I have to have my lips done right when I turn 18. If I could’ve done it sooner I would’ve and I don’t regret it,” she says. “I don’t think I’ve gone overboard like people claim.”

Zolciak-Biermann agrees with her daughter that people will attack them on social media for their choices no matter what.

“People always have something to say,” she says. “You’re never going to win.”

“I knew that it was coming,” Biermann says, of the lip injection backlash. “Everybody has an opinion, and some people say I’ve gone overboard. I will say, in some pictures, they do look a little crazy, but I feel like in person they’re actually not.”
